Let's divide 13923896 by 861
We want to divide 13923896 by 861.

On to step 1:
861 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 861

Let's proceed to step 2:
The number 861 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 861

Going ahead to step 3:
139 divided by 861 is 0 with a remainder of 139.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 139 to get 139.
Take the next digit (2) from the dividend and append it to 139, then repeat: 1392 / 861

On to step 4:
The number 861 fits into 1392 1 times, leaving a remainder of 531.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 861 from 1392 and we're left with 531.
Take the next digit (3) from the dividend and append it to 531, then repeat: 5313 / 861

On to step 5:
5313 divided by 861 is 6 with a remainder of 147.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 5166 from 5313 and we're left with 147.
Include the next digit (8) from the dividend after 147, then repeat: 1478 / 861

Advancing to step 6:
861 can be fit into 1478 1 times, resulting in a remainder of 617.
The number 1 becomes the next digit in our result. 
Result so far: 161.0
If we subtract 861 from 1478, we get 617.
Fetch the next digit (9) from the dividend, attach it to 617 and continue: 6179 / 861

Moving on to step 7:
861 goes into 6179 7 times with a remainder of 152.
Write down 7 as next digit of the result. 
Result so far: 1617.0
If we take 6027 away from 6179, we end up with 152.
Take the next digit (6) from the dividend and append it to 152, then repeat: 1526 / 861

Let's proceed to step 8:
861 can be fit into 1526 1 times, resulting in a remainder of 665.
Use 1 as the next digit of our solution. 
Result so far: 16171.0
If we subtract 861 from 1526, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 9:
When dividing 6650 by 861, we get 7 with a remainder of 623.
Record the quotient 7 as the next digit in the result. 
Result so far: 16171.7
If we subtract 6027 from 6650, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 10:
If we divide 6230 by 861, we get 7 and a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 16171.77
If we take 6027 away from 6230, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

The final result is 16171.77 with a remainder of 0.203.
